Metronomic Chemotherapy in Oral Cancer: A Review.

Treatment of locally advanced oral cancer requires multidisciplinary care, including surgery, radiotherapy, and chemotherapy, which varies based on the stage of the disease, site of involvement, and surgical access. Oral cancer usually presents with an increased recurrence rate and potential for distant metastatic spread. It confers a poor prognosis with a 50% mortality rate after five years. Oral metronomic chemotherapy aims to achieve higher patient compliance due to its ease of administration, lower dosage, and lesser side effects than conventional IV regimens of platinum-based drugs. In this review, we have summarized the relevant literature to benefit the readers regarding the potential application of metronomic therapy in the management of oral cancer.

Geospatial mapping of 2-hour access to timely essential surgery in the Philippines

ObjectivesTimely access to safe and affordable surgery is essential for universal health coverage. To date, there are no studies evaluating 2-hour access to Bellwether procedures (caesarean section, laparotomy, open fracture...

Penoscrotal approach for inflatable penile prosthesis implant: why it should be preferred.

Inflatable penile prosthesis are the definitive treatment for erectile dysfunction. The two most used surgical approaches to position the implants are the penoscrotal and the infrapubic. Current trends showed that the penoscrotal approach is extensively preferred however, there is not conclusive evidence demonstrating the superiority of one technique over the other. The aim of this review is to summarize the scientific evidence available and to underline strengths and weaknesses of the two techniques. We conducted a comprehensive search of MEDLINE, Cochrane Library, and National Center for Biotechnology Information PubMed to identify relevant published articles. The included studies had to explicitly examine the use of three-piece inflatable penile prosthesis with a focus on the surgical access method and complications. Twenty-six articles were included in the review: seven narrative reviews, five retrospective observational studies, five prospective observational studies, and nine mixed methodology studies. The most frequent approach was the penoscrotal, which was also found more comfortable (RG1) by the operators in one study. The infrapubic approach lasts less and one study demonstrated higher satisfaction by the patients. There is no evidence of significant differences in complications among the penoscrotal and infrapubic approaches. While the infrapubic approach is faster and patients were more satisfied, the penoscrotal approach is the most used by far. This is likely related to the more straightforward procedure through this access and the excellent surgical field exposure. For these reasons, it is also preferred in the most complex cases.

Application of a maxillary transfacial approach to the caudal oral cavity and orbitozygomaticomaxillary complex in dogs

Surgical access and visualization for excision of large pathologic lesions of the orbitozygomaticomaxillary complex (OZMC) and caudal oral cavity can be a challenge in veterinary oromaxillofacial surgery and may limit one’s ability to perform such procedures. Combined intra- and extra-oral approaches as well as commissurotomy have been advocated in the past. However, each of these approaches present unique limitations specific to each approach. A transfacial approach that ameliorated these limitations could be advantageous. In this descriptive cohort study, we investigate the application and outcomes of a maxillary transfacial approach to the OZMC and caudal oral cavity in six client-owned dogs. The approach is based on the Weber–Ferguson approach for human applications and provided excellent exposure of the intended region in all six patients. We contend the maxillary transfacial approach provides some advantages to the more conventional combined intra-oral/extra-oral approach or commissurotomy for excision of large pathologic lesions of the OZMC and caudal oral cavity.

Modified Mucosal Reconstruction in Unilateral Complete Cleft of Lip and Primary Palate: Surgical Technique and Practical Strategies.

The nasal floor and intraoral lining reconstruction of unilateral complete cleft of lip and primary palate has sparsely been reported. Solution: This article combines the previously-described C-flap mucosal flap and inferior turbinate flap with the newly-described lateral nasal mucosal flap for the mucosal repair of this uncommon subtype of deformity. Valuable practical strategies are offered to optimize the surgical execution within a limited pediatric intranasal surgical access, targeting to minimize tissue trauma and bleeding.

Health Status of Total Hip Versus Total Knee Arthroplasty Patients and Possible Effects on Decisions Regarding Surgical Location, Cost, and Access to Care.

Background: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are no longer considered inpatient-only procedures. Qualifying for inpatient status reimbursement requires additional, unreimbursed administrative effort, and may limit care to these patients. Purpose: We sought to evaluate and compare the overall health status of patients receiving THA and TKA. Methods: We conducted a retrospective review evaluating 2207 patients undergoing primary THA and TKA from 2015 to 2018 at a single institution. Clinical parameters, surgical procedure, medical history, laboratory values, length of stay (LOS), and discharge location were recorded and compared between the 2 groups. Results: In 2202 patients, we observed differences for body mass index (THA = 29.4 ± 0.4, TKA = 32.1 ± 0.3), low-density lipoprotein cholesterol levels (THA = 105.8 ± 13.5 mg/dL; TKA = 128.6 ± 13.7 mg/dL), and blood glucose levels (THA = 98.2 ± 1.7 mg/dL; TKA = 101.4 ± 1.3 mg/dL), indicating that TKA patients were more likely than THA patients to be classified as obese, hypercholesterolemic, and hyperglycemic. We observed longer LOS in THA patients (51.25 hours, 95% CI ± 3.87 hours) than in TKA patients (36.93 hours, 95% CI ± 1.17 hours). A greater proportion of TKA patients were discharged home (81.97%, N = 1155) rather than to additional care facilities compared with THA patients (71.84%, N = 539). Conclusion: In this retrospective study, we observed that TKA patients had higher rates of comorbidities than did THA patients, but TKA patients spent less time in the hospital and were more likely to be discharged home. Future studies should evaluate reasons for poor clinical outcomes for patients undergoing total joint arthroplasty with an outpatient designation.

Robot-Assisted Thoracofemoral Bifurcation Bypass

INTRODUCTION: Thoracofemoral bypass surgery for occlusion of aortofemoral segment is a variant of choice for treatment of patients with impossibility of performing traditional aortofemoral bypass. The use of robot-assisted technologies in the formation of a proximal anastomosis permits to reduce the trauma of surgical access and to improve the results of surgical intervention. The article reports a case of a patient with occlusion of the aorto-iliac segment and total calcification of the infrarenal aorta, who underwent robot-assisted thoracofemoral bifurcation bypass surgery.
 CONCLUSION: Use of modern technologies in the vascular surgery permits to reduce traumatization, minimize the effect of the human factor, improve visualization and freedom of movement and shorten the recovery period and the period of hospital stay.

The role of civil society and the voluntary sector in children's global surgery

An unacceptable inequity exists in the burden of pediatric surgical disease and access to surgical and anesthesia care between low- and middle-income countries (LMIC) and high-income countries (HIC). Civil society organizations (CSOs) and the voluntary sector have been integral in addressing this imbalance. This article summarizes the roles that these organizations have played in improving pediatric surgical care globally and how their roles have evolved over the years. CSOs and voluntary organizations have historically provided operations on LMIC patients; however, the focus has shifted to building sustainable surgical systems by training a skilled workforce, improving local infrastructure, and contributing to research and advocacy efforts.

Surgical access in treatment of kidney cancer complicated by tumor thrombosis of the inferior vena cava and right atrium

This article discusses the choice of surgical access in renal cancer complicated by tumor thrombus with invasion into the inferior vena cava and the right atrium. This clinical scenario poses a major challenge to the surgeons, as tumor thrombus can obstruct access to the surgical area and increase the risk of complications. This article discusses various surgical access techniques that can be used in treatment of kidney cancer complicated by tumor thrombus of the inferior vena cava and right atrium, including open surgery, robotic surgery, and minimally invasive techniques. An analysis of factors to consider in selection of the optimal surgical access was perfomed.

Estimating access to surgical care: A community centered national household survey from Pakistan.

Pakistan is a lower middle-income country in South Asia with a population of 225 million. No estimate for surgical care access exists for the country. We postulate the estimated access to surgical care is less than the minimum 80% to be achieved by 2030. We conducted a randomized, stratified two-stage cluster household survey. A sample of 770 households was selected using 2017 census frames from the Pakistan Bureau of Statistics. Data was collected on choice of hospital and travel time to the chosen hospital for C-section, laparotomy, open fracture repair (OFR), and specialized surgery. Analysis was conducted using Stata 14. Access to all Bellwether surgeries (C-section, laparotomy, and open fracture repair) in Pakistan is estimated to be 74.8%. However, estimated access in rural areas and the provinces of Balochistan, Khyber Pakhtunkhwa (KP) and Sindh is far less than in urban areas and in Punjab and Islamabad. Estimated access to C-sections is more compared to OFR, laparotomy, and specialized surgery. Health system strengthening efforts should focus on improving surgical care access in rural areas and in Balochistan, KP, and Sindh. More focus is required on standardizing the availability and quality of surgical services in secondary-level hospitals.

Solitary Fibrous Tumours of the Orbit - Clinical Pathology, Therapy and Prognosis.

Solitary fibrous tumours are rare. The aim of this study is to describe the clinical features, therapy and outcome of affected patients and to identify factors associated with recurrence. Retrospective study of a cohort of 20 patients who underwent surgery for orbital solitary fibrous tumour at the University Department of Oral and Maxillofacial Surgery between 2002 and 2023. Demographic, clinical, and therapeutic data as well as tumour follow-up results were collected. Tumour volume and molecular genetic mutations were retrospectively determined. The median patient age was 49.5 years at initial surgery. The left orbit was affected in 65% of cases. The most common clinical symptom was proptosis (80%). This was reported with a mean lateral difference of 3.9 mm (range: 1 - 10 mm). The tumours were localised predominantly in the intra- and extraconal space, craniolateral quadrant and middle third. The median tumour volume was 7.66 cm³ (range 2.15 - 12.57 cm³). In all patients, the diagnosis was made by pathological examination. All tumours investigated showed a NAB2-STAT6 mutation. The most frequently detected mutation was the fusion NAB2 exon 4 - STAT6 exon 2. All patients were initially managed with frontolateral orbitotomy. Incomplete resection (R1-status) occurred in 35% (n = 7). The recurrence rate was 25% (n = 5), with a median disease-free interval of 45.5 months (range 23 - 130). 80% (n = 4) of recurrences were initially R1-resected. Orbital solitary fibrous tumours are rare tumours and are clinically manifested by signs of displacement of orbital structures. Diagnosis is made by histology and immunohistochemistry and can be proven with the molecular genetic detection of the NAB2-STAT6 mutation. The therapy of choice is complete surgical resection. R1-resection is more likely in the intraconal location as well as in location in the posterior third of the orbit - due to difficult surgical accessibility. The greatest risk factor for the development of recurrence is incomplete surgical excision. Late recurrences are possible, which is why a long-term connection to a specialised clinic is necessary.

Functional Magnetic Resonance Imaging and Diffusion Tensor Imaging-Tractography in Resective Brain Surgery: Lesion Coverage Strategies and Patient Outcomes.

Diffusion tensor imaging (DTI)-tractography and functional magnetic resonance imaging (fMRI) have dynamically entered the presurgical evaluation context of brain surgery during the past decades, providing novel perspectives in surgical planning and lesion access approaches. However, their application in the presurgical setting requires significant time and effort and increased costs, thereby raising questions regarding efficiency and best use. In this work, we set out to evaluate DTI-tractography and combined fMRI/DTI-tractography during intra-operative neuronavigation in resective brain surgery using lesion-related preoperative neurological deficit (PND) outcomes as metrics. We retrospectively reviewed medical records of 252 consecutive patients admitted for brain surgery. Standard anatomical neuroimaging protocols were performed in 127 patients, 69 patients had additional DTI-tractography, and 56 had combined DTI-tractography/fMRI. fMRI procedures involved language, motor, somatic sensory, sensorimotor and visual mapping. DTI-tractography involved fiber tracking of the motor, sensory, language and visual pathways. At 1 month postoperatively, DTI-tractography patients were more likely to present either improvement or preservation of PNDs (p = 0.004 and p = 0.007, respectively). At 6 months, combined DTI-tractography/fMRI patients were more likely to experience complete PND resolution (p < 0.001). Low-grade lesion patients (N = 102) with combined DTI-tractography/fMRI were more likely to experience complete resolution of PNDs at 1 and 6 months (p = 0.001 and p < 0.001, respectively). High-grade lesion patients (N = 140) with combined DTI-tractography/fMRI were more likely to have PNDs resolved at 6 months (p = 0.005). Patients with motor symptoms (N = 80) were more likely to experience complete remission of PNDs at 6 months with DTI-tractography or combined DTI-tractography/fMRI (p = 0.008 and p = 0.004, respectively), without significant difference between the two imaging protocols (p = 1). Patients with sensory symptoms (N = 44) were more likely to experience complete PND remission at 6 months with combined DTI-tractography/fMRI (p = 0.004). The intraoperative neuroimaging modality did not have a significant effect in patients with preoperative seizures (N = 47). Lack of PND worsening was observed at 6 month follow-up in patients with combined DTI-tractography/fMRI. Our results strongly support the combined use of DTI-tractography and fMRI in patients undergoing resective brain surgery for improving their postoperative clinical profile.

Angiogenic gene therapy for refractory angina: results of the epicardial delivery of XC001 gene therapy for refractory angina coronary treatment (EXACT) phase 2 trial

Abstract Background Refractory or "no option" angina (RA) is a debilitating condition with increasing global prevalence. Exogenous transduction of vascular endothelial growth factor (VEGF) induces angiogenesis and improves perfusion of ischemic myocardium in preclinical studies. XC001 (AdVEGFXC1) is a novel adenoviral-5 vector expressing the three major isoforms of VEGF (-121, -165, -189) in ratios shown to enhance potency and improve safety. Purpose EXACT is a single-arm, multicenter, open-label, phase 2 trial to explore the safety, tolerability, and preliminary efficacy of trans-epicardial delivery of XC001 to improve exercise capacity and ischemic burden in RA patients. Methods Patients were required to have stable Canadian Cardiovascular Society (CCS) class II-IV angina on maximally tolerated medical therapy with exercise limited by angina after 90 but before 540 seconds on a modified Bruce protocol, demonstrable ischemia on stress positron emission tomography (PET) and lack revascularization options. XC001 (1x1011 viral particles) was injected directly into ischemic myocardium via surgical transthoracic epicardial access. The primary outcome was safety by adverse event monitoring. Efficacy assessments included difference from baseline to six months in total exercise time (TET), myocardial ischemia by PET, angina class, angina frequency, and quality of life. Results Thirty-two patients (mean/median ages of 64/64, 34% female) were enrolled at 13 sites between March 2021 and July 2022. Median anti-anginal use was 3, 75% had prior revascularization with CABG and 88% with PCI. Fifty-five serious adverse events (SAEs) were observed in 21 patients (66%). None were attributed to study drug. Twenty-one SAEs in 14 patients were related to the surgical procedure, all of which were expected. One non-CV death occurred in month 3 following respiratory infection (Covid) deemed unrelated to surgery or study drug. Compared to baseline, total exercise time at 6-months increased by 85.5 seconds (95% CI 31.3-139.7) [Figure 1A] while total myocardial ischemic deficit in the treated region on PET decreased by 14.4% (95% CI, 3.01–25.73) [Figure 1B]. Angina frequency and nitroglycerin use measured during a two-week diary decreased by 6.6 episodes (95% CI, 3.5–9.7) and 4.1 doses (95% CI, 1.3–6.9), respectively. Canadian Cardiovascular Society angina grade decreased from 3.1 to 1.8, mean difference 1.3 classes (95% CI, 1.0–1.6) [Figure 2] while Seattle Angina Questionnaire Frequency score improved from 41.3 to 67.4, mean difference of 26.1 (95% CI, 16.3–35.9). Conclusions VEGF gene therapy with XC001 administered via minimally invasive epicardial delivery appears safe and well tolerated. Improvements in objective and subjective measures including total exercise time, myocardial perfusion, angina frequency and quality of life support a clinically meaningful biologic effect. This therapy warrants study in larger randomized studies.

An alternative surgical access for posterior tracheal defects or fistulae situated between the cervical and thoracic region.

Posterior tracheal lesion defects between the cervical and the thoracic region represent a surgical challenge. Cervicotomy or median sternotomy might not allow a satisfactory exposure of the defect, and a history of prior neck surgeries could further complicate the procedure. We propose a high posterior right thoracotomic approach, by which the entire posterior aspect of the trachea is visible, up to the cervical region. We describe our experience with this approach, which is best suited for cases where a non-circumferential repair of the trachea is attempted.

SCIENTIFIC UPDATE ON POST-OPERATIVE PAIN MANAGEMENT IN ORTHOPEDIC SURGERY

Postoperative pain results from the nociceptive stimulus caused by the surgical aggression, coming from direct or indirect mechanisms. Its intensity and duration depends on several factors, mainly the type of surgical approach, surgical access and anatomy. Orthopaedic surgeries are considered one of the most painful, due to the intense nociceptive stimulation of the musculoskeletal tissue.The prevalence of post-operative pain is described in 73% of patients who experience moderate to severe pain on the first day after surgery. A lower prevalence is observed in developed countries, due to pain protocols, the presence of acute pain services and advanced general anesthesia techniques. Numerous protocols have been tested, and opioids are often the drugs of choice, but the events are considered the biggest drawback. Pain control can be achieved through the use of certain medications, the use of physical means and interventions related to cognitive behavior, such as educational techniques and relaxation. Even though it is difficult to treat pain, analgesic methods are essential to reduce the incidence of persistent pain, avoiding and alleviating future chronic pain conditions that are difficult to treat.

Percutaneous elastic-dynamic fixation for the treatment of volar displaced distal radius fractures. A solution for elderly patients?

&amp;lt;p&amp;gt;&amp;lt;strong&amp;gt;Aim&amp;lt;/strong&amp;gt; &amp;lt;br /&amp;gt;The Epibloc elastic-dynamic fixation has been applied for many years at several hand surgery centres in Italy. This technique has been considered safe and reliable in the treatment of distal meta-epiphyseal fractures of the radius with dorsal displacement. The aim of this study was to evaluate an alternative use of this method in the treatment of volar displaced wrist fractures in cases where an internal fixation could not be recommended.&amp;lt;br /&amp;gt;&amp;lt;strong&amp;gt;Methods &amp;lt;/strong&amp;gt;&amp;lt;br /&amp;gt;The procedure consisted of two flexible pins with a trocar tip and an external plate for locking fixation with compression.&amp;lt;br /&amp;gt;The surgical technique was derived from the original procedure, modifying the placement of the pins and performing small surgical accesses to preserve the neuro-vascular structures of the volar aspect of the wrist. To achieve and preserve the reduction of the volar fragment, a third pin was inserted into the fracture with a similar procedure to Kapandji&amp;#039;s reduction technique.&amp;lt;br /&amp;gt;&amp;lt;strong&amp;gt;Results&amp;lt;/strong&amp;gt; &amp;lt;br /&amp;gt;At three-month follow-up, most patients did not experience any pain. In 14 cases, the strength grip was recovered between 75% and 90%, compared to the contralateral hand (Jamar test). In 15 patients, the wrist range of motion was restored with values greater than 100. In 17 cases, forearm pronation-supination was restored to more than 120&amp;amp;deg;.&amp;lt;br /&amp;gt;&amp;lt;strong&amp;gt;Conclusion&amp;lt;/strong&amp;gt; &amp;lt;br /&amp;gt;In cases of non-comminuted, one or two fragments volar displaced wrist fractures, the elastic-dynamic fixation associated with an intrafocal pinning reduction may be proposed as an alternative to open reduction and internal fixation in elderly&amp;lt;br /&amp;gt;patients.&amp;lt;/p&amp;gt;

Association between underweight status and chylothorax after esophagectomy for esophageal cancer: A propensity score–matched analysis

ObjectiveTo use a nationwide database of hospitalizations to investigate underweight status as a risk factor for postesophagectomy complications. MethodsWe identified all patients who underwent esophagectomy with a diagnosis of esophageal cancer and known body mass index in the 2018-2020 Nationwide Readmissions Database. All hospital visits for esophagectomy and within 30 days of initial discharge were analyzed for postoperative complications, including chylothorax. Patients who were underweight were propensity score matched with patients who were not. Multivariable logistic regression was performed to identify complications that were significantly associated with underweight status. ResultsThere were 1877 patients with esophageal cancer meeting inclusion criteria. Following propensity score matching, 433 patients who were underweight were matched to 433 patients who were not. In the multivariable model of the matched sample, which adjusted for age, sex, Charlson Comorbidity Index, history of chemotherapy or radiation therapy, and preoperative surgical feeding access, patients who were underweight were estimated to have 2.06 times the odds for chylothorax (95% confidence interval [CI], 1.07-4.25, P = .035). Underweight status was also significantly associated with acute bleed (odds ratio [OR], 1.52; 95% CI, 1.12-2.05, P = .007), pneumothorax (OR, 2.33; 95% CI, 1.19-4.85; P = .017), pneumonia (OR, 2.30; 95% CI, 1.53-3.50, P < .001), and in-hospital mortality (OR, 2.42; 95% CI, 1.31-4.69, P = .006). ConclusionsUnderweight status was found to be a risk factor for chylothorax after esophagectomy, which may have implications for perioperative care of esophageal cancer patients. Future studies should assess whether using feeding tubes or total parenteral nutrition preoperatively or thoracic duct ligation intraoperatively decreases risk of chylothorax among patients who were underweight.

Factores que afectan la calidad de vida en pacientes pediátricos con y sin cirugía cardiaca

Introduction and objectivesAs the survival of children with congenital heart disease who have undergone cardiac surgery has increased significantly, the need for follow-up in terms of health related quality of life has become increasingly important. In this study, we sought to describe the health related quality of life in children with congenital heart disease with and without surgical repair. MethodsWe applied the Pediatric Quality of Life Inventory (PedsQLTM) questionary in 271 patients aged 2 to 17 years, of the patients who attended the cardiology clinic both pre surgery and postsurgery. Health related quality of life was expressed as a total score (highest 100) and provided as medians and percentages from 10 to 100. ResultsWe included 271 patients from 2 to 17 years old, 94.8% had a biventricular heart. Cardiac surgery was performed in 67.8% The main factor that negatively affected quality of life were univentricular physiology, the presence of residual shunt, requiring another surgery, management with polidrugs, and surgical access through median sternotomy. ConclusionPatients with congenital heart disease nor only suffer from their main disease, but also experience a quality of life that can be affected by social, educational and emotional factors. The assessment of quality of life by health professionals should be an integral part of the evaluation of these patients.

Roles of nurse-surgeons in global surgical care: A scoping review.

To identify the roles of nurse-surgeons in the provision of surgical care. Scoping review. This scoping review adhered to the JBI guideline for scoping reviews and EQUATOR Network's PRISMA-ScR checklist. Searches were performed from May 2022 to July 2022 using a combination of MeSH headings, keywords and filters via database and hand searching based on the eligibility criteria. Keywords included nurse-surgeon, nurse endoscopist, nurse hysteroscopist and nurse cystoscopist. Data sources were CINAHL, Cochrane, Google Scholar, PubMed and Scopus. Descriptive analysis was used to report the findings. Ninety-six included records indicated nurse-surgeon practice in 26 countries. Forty-one nurse-surgeon titles were found, the majority of which were types of nurse practitioner. A total of 5,684,198 surgeries were performed by nurse-surgeons varying from laparotomies to biopsies. Nine records reported that nurse-surgeons perform surgeries safely and on par with physicians with zero to minimal complications. Nineteen records reported improved surgical care efficiency by nurse-surgeons in terms of patient access to surgery, waiting times, surgery times, patient show rates, patient education, physician workload and junior physicians' training. Seven records reported high patient satisfaction. Nurse-surgeons were cost-effective according to five records. Thirteen records recommended the standardization of nurse-surgeon practice. Nurse-surgeons performed millions of surgeries worldwide assisting in easing the global surgical burden. This review identified the roles and benefits nurse-surgeons play in global surgical care. Research gaps on nurse-surgeon roles were discovered including the ambiguity in nurse-surgeon titles and the need to regulate nurse-surgeon practice. This research addressed the clinical safety, quality, contribution to timely surgical access and cost efficiency of nurse-surgeon performed surgeries, as well as the need to standardize nurse-surgeon practice and use a more consistent nurse-surgeon title to ensure role identification and monitoring.
